Thank you all for your comments. USGBC is indeed listening!

I know many comments have mentioned the poll at Greenbuild. While the survey was one factor in the decision, the overwhelming factor is that fewer than 400 projects have registered for LEED v4 despite it being in the market for more than 12 months. In the first 12 months of LEED 2009 being in the market, nearly 5,000 projects had registered. The message that USGBC has received is loud and clear – the market needs additional time.

Extending LEED 2009’s availability for an additional 15 months enables USGBC to work with the broader industry within a longer time frame to drive meaningful and comprehensive change. This move helps ensure that LEED remains the most used green building standard up until that time so that we can continue to drive the most impactful change possible. The additional time also helps international LEED users keep pace with us – which is critical. By the time we fully transition to v4 we will have an even more committed and robust international audience

Many of the comments have also suggested that v4 is on a delay – LEED v4 is not on a delay – it is open and available for use.

We see this to be a great opportunity for leaders to become early adopters of v4. Project teams, owners, and supportive manufacturers are continuing to work on LEED v4, and know they will reap the rewards of being first to market, and will provide leadership for others.
